Summary: Gypsum precipitation in groundwater wells during CO2 injection can pose a potential clogging hazard. The precipitation is primarily caused by changes in water saturation due to CO2 injection and the release of Ca2+ ions from dolomite dissolution. Gypsum precipitation decreases with increasing temperature but increases with increasing partial CO2 pressure.

Summary: The study demonstrates significant alterations in the mineral phase of deep reservoirs after CO2 injection, particularly in terms of precipitation/dissolution reactions of silicates and carbonates. The sequence of changes in different minerals varies at different stages, while the uncertainty of mineral saturation is mainly influenced by variations in water chemical composition and database records.

Summary: The feasibility of N2 alternating CO2 injection for improving CO2 storage and oil production was investigated through laboratory experiments and numerical simulation. The results showed that the N2 alternating CO2 flooding had 2.1% lower CO2 storage factor and 7.1% lower enhanced oil recovery compared to continuous CO2 injection. However, the larger the N2 slug volume, the lower the EOR and CO2 storage factor, due to the reduction of CO2 concentration in the gas phase and CO2 solubility in oil and water. Nevertheless, the N2 slugs significantly reduced mobility differences between flowing zones, resulting in a 1.78 times larger gas swept area and a 44% higher cumulative oil production compared to continuous CO2 injection. Moreover, the optimized N2 alternating CO2 injection scheme achieved 19.6% more CO2 storage than continuous CO2 flooding at a field scale. This study provides valuable experimental and theoretical support for improving CO2 storage and oil production in an oil reservoir.

Summary: The study demonstrates that impurities in CO2 streams can have an impact on enhanced oil recovery and carbon capture and storage performance. Different types and concentrations of impurities affect the maximum miscibility pressure (MMP) of the oil-gas mixture, leading to decreased displacement efficiency and reduced oil density.

Summary: The study investigated the dynamics of a CO2 injection wellbore using a fully-coupled non-isothermal transient multiphase wellbore-reservoir flow model. It found that the build-up of liquid CO2 in the wellbore significantly increases bottom hole pressure, and that the mean permeability of the target formation layer plays a crucial role in controlling wellbore transient functions. By redesigning injection tests and performing history-matching, the study provides insights into monitoring injection performance and wellbore behavior during CO2 injection scenarios.

Summary: The study found that the location of the injection well influences the CO2 storage efficiency, depending on the reservoir properties of the geological structures. For structures with good reservoir properties, greater distance from the top of the structure and greater depth difference result in higher storage efficiency; the opposite is true for structures with poor reservoir properties.

Summary: In this study, microfluidic experiments were conducted to investigate the mixing and flow behavior of oil and CO2 in porous media with dead-end pores. A novel oil-CO2 miscible flow model was established based on the experimental observation, which can describe the effects of diffusion, flow velocity distribution, fluid properties change, and pore structures on oil-CO2 mixing and oil displacement. The modeling results indicate that diffusion plays an important role in oil-CO2 mixing, especially in deep dead-end pores.

Summary: This article investigates the challenges of CO2 storage in coal and proposes a novel solution. Through pre-operational simulation studies, it is found that the targeted amount of CO2 can be injected into the coal seams without significant loss of permeability or injectivity by varying the length of horizontal wells and injection conditions. Furthermore, the spread of CO2 is predicted to be contained within the model domain.

Summary: Carbon capture and storage is an important technology for reducing environmental impact and achieving climate change goals. However, there are significant challenges in designing and modeling carbon sequestration projects, including assessing risks and long-term consequences. This study uses a reservoir simulator to model the evolution of CO2 injection in an experimental setup and proposes an ensemble-based approach to quantify uncertainties and study the predictability of numerical models.

Summary: The aim of this study is to investigate the response of dry stone walls to out-of-plane forces and the impact of block's rugosity, joint arrangement, and border conditions. Experimental tests and 3D numerical modeling using discrete elements (DEM) were conducted to analyze the effects of joint disposition and border conditions on the response. The results indicate that the DEM method is suitable for simulating the failure mode, displacement, and lateral load of stone walls due to out-of-plane lateral loads.

Summary: Extensive research has been conducted on the vegetation, geographic distribution, and pastoralist uses of peatlands in the central Andes over the past two decades. However, there is a lack of information regarding the hydrologic processes that support these ecosystems and the alterations caused by human activities or climate changes. This limitation hampers our understanding of how the central Andean Puna, one of the world's most threatened ecoregions, may be affected by increasing temperatures and water extraction. Furthermore, overgrazing plays a significant role in modifying the ecological trajectories of these peatlands.

Summary: This article investigates the impacts of groundwater management policies on the Caplina aquifer located in the Atacama Desert, Peru. The results show that the current and future conditions of the groundwater in the Caplina aquifer are not sustainable, and public policies are not effective for reversing this situation. This leads to a situation where there is a quality degradation of the water in the aquifer, to a potentially irreversible point.
